What is the best way to solve the equation x^2=k

"Best way to solve this equation" is very, very broad.

You could solve this equation two ways:

You could solve for x, or you could solve for k.

K has already been solved for, as it is equal to x^2.

We can also solve for x.

x = √k

the answer is 24

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
